Two Things to Avoid when Compiling GDP
Multiple counting Only expenditures on final products – what consumers, businesses, and government units buy for their own use belong in GDP Intermediate goods are not counted Used goods are not counted
5
Two Things to Avoid when Compiling GDP
Transfer payments Transfer payments are not payments for currently produced goods and services When they are spent for final goods and services they will go into GDP as consumer spending Financial transactions don’t go into GDP
6
Why only Final Goods Counting the sale of final goods and intermediate products would result in double and triple counting.
7
What is counted? What is not?
The cost of the parts is included in the final sale price So they are not counted when the manufacturer buys them. Only the value of the final sale is counted.
8
This is confusing! The tires that come with the car is not counted as a final good However if you get a flat and buy the same tire it is counted as a final good
9
No Problem! To correct for this problem economist have created the Value Added approach.
10
Value Added Approach Eliminates Double Counting
11
The Value-added Approach to Measuring GDP
Production Generated Added Farmer harvest wheat $ $100 Miller makes into flour Baker makes into bread $ $300 GDP counts only the $ value of the final good This is the same as the “value-added.” 9-25 Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved.

Calculating GDP GDP can be calculated three ways:
add up the value added of all producers; add up all spending on domestically produced final goods and services, leading to the equation: GDP = C+I+G+X-IM; add up the all income paid to factors of production
13
Calculating GDP In this hypothetical economy consisting of three firms, GDP can be calculated in three different ways: Measuring GDP as the value of production of final goods and services, by summing each firm’s value added; measuring GDP as spending on domestically produced final goods and services, and measuring GDP as factor income earned from firms in the economy.
